SAN FRANCISCO (KGO) -- A big blow for the tobacco industry -- the government tightened rules for e-cigarettes nationwide and California raised the legal age to buy any tobacco products to 21.

The owner of San Francisco's Magic Dragon smoke shop kicked out some young customers for not having their IDs. The law states that anyone under 18 can't enter. That will change as of June 9 when California will raise the legal age to buy tobacco for smoking, dipping, chewing, and vaping from 18 to 21.
